ABSTRACT
Using a magneto-optical indicator film imaging technique and an x-ray topography, we have observed a strong correlation between magnetic and twin structure of a single crystal of La[sub 0.7]Sr[sub 0.3]MnO[sub 3] (LSMO). The correlation between magnetic and twin domains can be understood in terms of a rhombohedral deformation of the cubic cell of LSMO which is accompanied by an occurrence of a magnetic anisotropy. Our data and analysis suggest that twin domains play a fundamental role in a low-field magnetization behavior and in magnetotransport properties of LSMO. © 2000 American Institute of Physics.

    We experimentally demonstrate that the stress-induced magnetic anisotropy in composition-graded ferromagnetic NiFeTa layers can be employed to trigger exchange bias in NiFeTa/IrMn bilayers without using any deposition field or field cooling procedure. In particular, we found that the NiFeTa/IrMn...

    The effect of annealing under applied stress on magnetic properties of Co-based or CoFeNi-based glass-coated microwires was studied. It was found that CoFeNi-based microwires became bistable after annealing because of changing of magnetostriction constant sign, while Cobased microwires keep...

    Devices based on mesas were fabricated from thin films of magnetically phase-separated La0.6Ca0.4MnO3. Low-field magnetoresistance arises because the volume fraction of the ferromagnetic metallic phase is large enough for percolation but small enough to permit magnetic decoupling between each...

    It is observed that in single-crystalline yttrium iron garnet the amplitude of characteristic flexural oscillations of a 180° domain wall containing Bloch lines increases sharply when drift of the Bloch lines is excited. The resonance frequencies of these oscillations are virtually identical...
