摘要：
Detailed magnetic, magnetotransport, and magnetocaloric measurements on HoRu2Si2 have been performed. In this Letter, we report presence of spin reorientation transition below paramagnetic to antiferromagnetic transition temperature (T-N = 19 K). Large magnetic entropy change 9.1 J/kg K and large negative magnetoresistance similar to 21% in a magnetic field of 5 T has been observed around T-N, which is associated with field induced spin-flip metamagnetic transition.
