In a 4f−3d ferrimagnet the molecular field (a net value expressing the relevant exchange interactions) can be determined from high-field magnetization measurements. If the applied field is high enough, it breaks the ferrimagnetic ground state and drives the system towards ferromagnetic order via non-collinear intermediate phases. Magnetization curves of Er2Fe17 singe crystal were measured along...

First-principles and model calculations show that the Dirac surface state of the topological insulator Bi(2)Te(3) survives upon moderate Mn doping of the surface layers but can lose its topological character as a function of magnetization direction. The dispersion depends considerably on the direction of the Mn magnetization: for perpendicular magnetization, a gap of 16 meV opens up at the Dira...

The Hall resistivity, electrical resistivity, and magnetization of single crystals of the tetragonal ferromagnet Yb14MnSb11 are reported as a function of the direction of the current I and magnetic field H with respect to the principal crystallographic axes. With I along the unique c direction and H in the a-b plane, the anomalous Hall resistivity in the limit of zero applied field is negative ...

A domain is a region in a ferromagnetic material with the magnetization along a given direction. A magnetic material contains many domains with different magnetizations pointing in different directions in order to minimize the total magnetostatic energy. Regions with different orientations of their magnetization can be close to one another albeit with a boundary called a domain wall (containing...

The magnetization switching of Co0 25Pd0 75 alloy film on Pb(Zr0 52Ti0 48)O3 substrate was studied by measuring the polar Kerr rotation hysteresis loops and their electric field dependencies. It was found that the direction of spontaneous magnetization in CoPd alloy film was easily controllable via the inverse piezoelectric effect of the lead zirconate titanate layer, judging from the change of...

Weak ferromagnetism of quasi-one-dimensional S = 1/2 antiferromagnet BaCu 2 Ge 2 O 7 is studied by the magnetization measurement. The spontaneous magnetization appears along the b axis below 8.8 K. The local symmetry between the intra-chain nearest neighbor spins allows the presence of Dzyaloshinskii-Moriya interaction, and the only possible spatial configuration of the weak ferromagnetic momen...

I n the hard disk of a computer, the memory is stored in the local direction of the magnetization of a magnetic alloy. Here, just two directions of the magnetization (e.g., parallel and antiparallel to the disk) are used. Magnets can, however, form much more complex structures. Examples are bubble domains (1), where in thin magnetic layers, a regular arrangement of magnetic bubbles is induced b...

The interpretation of magnetic field data at low magnetic latitudes is difficult because the vector nature of the magnetic field increases the complexity of anomalies from magnetic rocks. The most obvious approach to this problem is to reduce the data to the magnetic pole, where the presumably vertical magnetization vector will simplify observed anomalies. However, RTP requires special treatmen...

The phenomena based on spin-orbit interaction in heavy metal/ferromagnet/oxide structures have been investigated extensively due to their applicability to the manipulation of the magnetization direction via the in-plane current. This implies the existence of an inverse effect, in which the conductivity in such structures should depend on the magnetization orientation. In this work, we report a ...
