Magnetocrystalline anisotropy of the multiphase samples of the hexaferrites Ba2Ni2-xCuxFe12O22 studied by the ferromagnetic resonance method

This paper presents structural and magnetic investigation of the hexaferrites Ba2Ni2-xCuxFe12O22 system in the Cu2+ concentration range 0 ≤ x ≤ 1.4. Samples were synthesized according to traditional ceramic processing technology. The samples were multiphase, since the optimal conditions of synthesis were not specially worked out. According to the data of X-ray diffraction analysis, the samples contain both a target phase and impurity phases of magnetite and hematite, as well as hexagonal phase of Ba-M. The values of the saturation magnetization of the samples were a little more than the values in the literature. It could be explained by the contribution from impurity phases with large magnetization values. The values of the anisotropy fields of the separate phases, which are contained in the investigated samples, were determined by the method of ferromagnetic resonance. The anisotropy field decreases with an increase in the content of copper ion. It is show that the value of the anisotropy field of hexaferrite Ni2Y is close to the literature value

Magnetic properties and structural characteristics of BaFe12O19 hexaferrites synthesized by the zol-gel combustion

The phase structure, structural parameters, and basic magnetic characteristics of BaFe12O19 hexaferrites prepared by the zol-gel combustion method with subsequent annealing at a temperature of 850°С for 6 h are investigated. The influence of the organic fuel type on the properties of synthesized materials is analyzed. Values of the saturation magnetization and the anisotropy field are determined. It is established that they depend on the organic fuel type. It is shown that powders synthesized with citric acid used as a fuel have the largest particle sizes and the highest saturation magnetization

Visit Sweden's market strategies : A bachelor thesis on Visit Sweden's choice of international markets compared to how the regional DMO:s priorities.

Huvudsyftet med denna uppsats är att förstå vad det finns för olika prioriteringar bland Visit Sweden och de regionala DMO:s när det kommer till en inriktning av den inkommande internationella turismen till Sverige. Vidare är vårt delsyfte att ta reda på hur samarbetet mellan Visit Sweden och de regionala destination managementorganisationer, s.k. DMO:s, förhåller sig och hör ihop med varandra. Vi har använt oss utav kvalitativ metod med olika former av intervjuer från de utförda intervjuerna med Visit Sweden och det regionala DMO:s samt även textmaterial från Visit Swedens webbsida. Teorierna är vetenskapliga artiklar som vi anser anknyter till det valda ämnet samt den insamlade empirin.  I resultaten utifrån den insamlade empiri framgår det att Visit Sweden inte ser själva att de väljer specifika marknader, men att de erkänner att de väljer fokusmarknader när det gäller de olika länderna. Visit Swedens val handlar bl.a. om de ser en potential att resenärer i respektive länder vill besöka Sverige. Detta kan ändras över tid beroende på interna och externa faktorer. De utgår främst utifrån deras målgrupp den Globala resenären som enligt deras marknadsanalyser kan appliceras på flera olika länder som inte ingår i deras fokusmarknader. Det som också styr deras val av marknader och marknadssegment är deras ägare svenska staten och svensk turism AB, men också olika turismaktörer såsom små och stora, som t.ex. hotell som efterfrågar att få hjälp med marknadsföring gentemot internationella turister. Gällande hur de regionala DMO:s prioriteringar ser ut i förhållande till Visit Sweden kan vi konstatera att de flesta prioriterar likartat i förhållande till Visit Sweden. Däremot ser vi ett mönster då de regionala DMO:s som inte delar samma val av fokusmarknader väljer att marknadsföra sig på andra sätt. Detta görs trots det finns en möjlighet för samarbete med Visit Sweden även om fokusmarknaden inte är densamma.Our main purpose with this bachelor thesis is to get an understanding of which different orientations currently exists when it comes to the incoming international tourism to Sweden. Furthermore, we want to find out how the collaboration between Visit Sweden and the regional destinations management organizations, called DMO:s is structured in relation to each other. We have chosen a qualitative method which includes several different types of interviews with Visit Sweden and the regional DMO:s as well as text material from Visit Sweden's website. The theories are scientific articles which we consider are suitable to our chosen subject and empirical data.     The results based on the collected empirical evidence show that Visit Sweden does not see that they have choose specific markets, but they admit that they choose focus markets when it comes to countries. Among other things, Visit Sweden's choice is about when they see a potential that travelers in each country want to visit Sweden. This can change over time depending on internal and external factors. They are based primarily on their target group Global Traveler who according to their market analyzes can be applied to several different countries that are not included in their focus markets. What also controls the selection of markets and market segments are their owners the Swedish state and Swedish tourism AB, but also various tourism stakeholders such as small and large, for example hotels who seek help with marketing towards international tourists. When it comes to how regional DMO:s prioritize compared to Visit Sweden we can conclude that several of them prioritize in the same way as Visit Sweden. However, we see a pattern when regional DMO:s who do not share the same choice of focus markets choose to market themselves in other ways than cooperating with Visit Sweden. This happens despite of the fact that there is an opportunity for collaboration with Visit Sweden still even if their focus market is not the same.
