= Low field magnetoresistance
{wiki=Low_field_magnetoresistance}
Low field magnetoresistance (LFMR) refers to the change in electrical resistance of a material when subjected to a weak external magnetic field. This phenomenon is often observed in certain types of materials, especially in ferromagnetic and semiconductor systems. \#\#\# Key Points: 1. **Definition**: LFMR involves a measurable change in resistance when exposed to a magnetic field that is relatively small compared to the magnetic fields usually involved in magnetoresistance studies.
