The resistivity of Pr 0.5 Ca 0.5 Mn 0.99 Cr 0.01 O 3 under H โ€ซุโ€ฌ 4 T shows unusual instability against thermal cycling between 250 and 5 K. The resistivity at 10 K change from 100 cm in the 5rst cycle to more than 10 6 cm in the 5fth cycle. However, magnetization decreases only by 1.2% between the 5
