摘要：

A study of the magnetic and electrical properties of some rare earth tetraborides (PrB4, SmB4, GdB4, TbB4, DyB4, HoB4, ErB4 and YbB4) was carried out on powders and single crystals prepared by the flux method. The tetraborides were found to be metallic. The only exceptions are PrB4 which is ferromagnetic and YbB4 where no magnetic ordering was found down to 0.34 K; they are antiferromagnetic at low temperatures. PrB4 and ErB4 have a strong anisotropy along the c axis from the susceptibility and magnetization measurements. ErB4 is of special interest because at low temperature it is antiferromagnetic in a weak magnetic field but shows two successive magnetic transitions with increasing field, leading finally to a purely ferromagnetic structure. © 1979.
