Abstract
We have synthesized CeRuSn single crystals and performed measurements of electrical resistivity and specific heat. At high temperatures, abrupt transitions were observed at 290 and 225 K in electrical resistivity during cooling.
Both transitions are connected with a large temperature hysteresis. Low temperature properties are dominated by an antiferromagnetic transition at 2.7 K, which involves only half of cerium ions, leaving the rest of them non-magnetic.
A significant magnetocrystalline anisotropy was revealed by application of external magnetic field.
