MAGNETORESISTANCE IN SEMICONDUCTORS TmxMn1-xS
This paper presents the results of measurements the electrical resistivity in solid solutions Tm<sub>x</sub>Mn<sub>1-x</sub>S, (x = 0.05, 0.15) with FCC NaCl type in the temperature range 80-400 K. Magnetoresistance changes sign from positive to negative in the room temperature.
