Induced Anisotropies in NiCo Obliquely Deposited Films and Their effect on Magnetic Domains

English Article: Oblique and in-plane anisotropies in obliquely evaporated NiCo thin films were investigated in order to understand their origin. All the compositions studied clearly show the effect of columnar grain morphology coupled with some intrinsic factors such as magnetostriction and crystallinity. Energy calculations are undertaken to explain the effect of

MAGNETOSTRICTION AND THERMAL EXPANSION OF CHROMIUM

On a mesuré le coefficient d'expansion thermique α = f(T) ainsi que les magnétostrictions longidutinale λ|| et perpendiculaire λ ⊥ du chrome entre 77 et 340 °K. On a montré que des transitions et des renversements de spins s'accompagnent d'une variation isotrope de volume. Il se produit une concentration thermique du chrome anormale entre 77 et 90 °K.The thermal expansion coefficient α = f(T) and longitudinal and transversal magnetostriction λ|| and λ ⊥ of chromium were measured between 77-340 °K. It has been shown that transitions through the temperatures and spin-flip are accompanied by isotropic change of the volume. Anomalous thermal contraction of chromium occurs between 77-90 °K
