Magnetic properties of MnP nanowhiskers grown by MBE

Abstract MnP nanowhiskers have been grown by molecular-beam epitaxy technique on the InP(100) surface. The measurements of the magnetization revealed that samples with MnP nanowhiskers exhibit ferromagnetic behavior up to room temperature. The investigation of temperature and angular dependences of ferromagnetic resonance has shown the existence of 90 degree anisotropy. The high values of coercive field and peak temperature obtained for the samples make it possible to consider such materials for potential applications in spintronic devices

MBE growth of nanowires using colloidal Ag nanoparticles

Ag colloidal nanoparticles are used as a catalyst for growth of GaAs nanowires by the molecular beam epitaxy on the Si(111) and GaAs(111)B substrate surfaces. The scanning electron microscopy measurements revealed that the nanowire formation occurs in different ways on different substrates, but the parameters of the synthesized nanowires open great prospects for their further use.Peer reviewe
