R-VSM and MOKE magnetometers for nanostructures

Two highly sensitive magnetometers: resonance-vibrating sample magnetometer and magneto-optical Kerr effect for hysteresis loop measurements of nanostructures are described. They are simple from the electronic point of view as well as from mechanical construction, the cost of designed instruments is very low in relation to commercial devices. The example measurement of minor hysteresis loops of MTJ is discussed.
