Manganese-based perovskite oxides are among materials known by their Colossal magnetoresistance (CMR) , exhibiting a dramatically change in their electrical resistance in the presence of a magnetic field. The magnetoresistance of conventional materials enables changes in resistance of up to 5%, but materials featuring CMR may demonstrate resistance changes by orders of magnitude.

for more details see for example :

Ramirez, A. P. (1997). "Colossal magnetoresistance". Journal of Physics: Condensed Matter. 9 (39): 8171. Bibcode:1997JPCM....9.8171R. doi:10.1088/0953-8984/9/39/005
