Electrical and magnetic properties of TmCoIn5 and YbCoIn5 single crystals

Electrical and magnetic properties of TmCoIn5 and YbCoIn5 single crystals were investigated by means of electrical resistivity and magnetization measurements in the temperature range from 300 to 0.5 K under the magnetic field up to 5 T. TmCoIn5 is an antiferromagnetic metal with a Néel temperature TN=2.6 K. YbCoIn5 shows non-magnetic behavior, reflecting of divalent Yb ion.
