The paper considers methodological aspects of formation of students' knowledge about the effects of a giant (GMR) and anisotropic (AMR) magnetoresistance as basic physical effects on which highly developed sensory information and nanoelectronics and spintronics devices. The technique demonstrations magnetoresistive effect film samples in CIP-geometry at room temperature. The use of two film samples (single-layer Co film and three-layer film Co/Cu/Co) of identical geometric sizes allows simultaneous demonstration of a typical anisotropic (single layer film) and a giant (three layer film) magnetic resistive at room temperature using a simple laboratory installation.
