摘要：

We present magnetoresistance measurements on the organic conductor alpha-(BEDT-TTF)(2)KHg(SCN)(4) in constant magnetic fields up to 21 T using the hybrid magnet. The resistance minimum in high fields suggests a possible existence of the new phase boundary in the normal metallic phase. It shows a slight temperature dependence around 10 K. The instability of the possible density wave states caused by the magnetic field is discussed with the presented magnetic phase diagram and the recent theoretical model.
