Magnetic and magneto-optic measurements (polar Kerr rotation and ellipticity) have been taken for a series of CoCrTa and CoCrPt single layer films with different thicknesses. The magnetic layers were rf sputter deposited onto constant thickness titan

Electron spin resonance spectra have been studied in partially crystallized films of La(1-x)Na(x)MnO(3) (x = 0.16) in the vicinity of the para- to ferromagnetic transition. The objects of investigation were obtained by magnetron sputtering on polycry

This letter deals with a magnetic tunnel junction having spin filtering by a magnetic barrier. We performed experiments in which a relatively strong external field rotates magnetizations of both ferromagnetic electrodes in the tunnel junction with th

The measurement of magnetostriction by the double-transducer technique has advantages of flexibility and sensitivity but is limited by sensitivity variations and phase shifts between transducers. This paper analyses technique limitations and shows ho

A new approach to the teaching of magnetic materials is afforded by a new teaching aid; the teaching aid enables magnetic domain changes for d.c. and a.c. magnetization to be shown on a television screen to large groups of students, demonstrating phe

The power loss of individual grains of silicon-iron in a polycrystalline sample has been measured using a thermal method, and the domain wall motion studied by the Kerr magneto-optic technique. The effect of applied stresses (0 ± 7 x 106 N. m-2) on

Magnetoresistive thin‐film sensors used in magnetic recording applications are often linearized using a transverse biasing field. For single‐domain behavior the biasing field is computed as the average planar value throughout the volume of the se
