DiboridesAB2crystallizing in the hexagonal C32 structure exhibit a wide range of magnetic and electronic properties depending on the choice of the elementAand the precise values of the lattice constantsaandc. ErB2represents a typical rare-earth diboride, exhibiting easy-plane ferromagnetic order below 14 K. We report a study of the evolution of the electrical transport properties of ErB2when tuning the lattice constants under pressures up to 5.6 GPa. Using Bridgman-type pressure cells with polycrystalline diamond anvils and steatite as the solid pressure medium, quasi-hydrostatic conditions are provided. We find that magnetic order is stabilized under pressure and discuss the influence of uniaxial components by comparing measurements on polycrystalline and single-crystalline samples.
期刊介绍：
Journal of Physics: Condensed Matter covers the whole of condensed matter physics including soft condensed matter and nanostructures. Papers may report experimental, theoretical and simulation studies. Note that papers must contain fundamental condensed matter science: papers reporting methods of materials preparation or properties of materials without novel condensed matter content will not be accepted.
