THE APPLICATION OF HIGH MAGNETIC-FIELDS IN SOLID-STATE PHYSICS

Frontiers in High Magnetic Fields may induce Frontiers in Materials En gineering and vice versa especially for materials combining semiconduc tor and magnetic properties in semimagnetic semiconductors. ZnMn2As2 i s a new material of the class (Zn1-xMn(x))3As2. For x = 2/3, however, the usual statistical substitution of the Zn-ion by Mn2+ condenses int o an ordered layer structure. The different magnetic phases are determ ined by neutron scattering, compared with low temperature magnetizatio n data and detected directly in the DC-magnetoresistance of the low mo bility holes, whose conductivity properties are essentially determined by the internal spin polarization of the material.
