To estimate specific power losses (SPL) of bulky magnetic hyperthermia heating mediators, a hysteresis loop measurement system in alternating magnetic field at a constant temperature was fabricated. Magnetic properties of a rectangular sample of La-Sr-Mn-Cu perovskite (LSMC) in a temperature range of 20~46 o C were estimated from induced electromotive force which arose in a single turn pickup coil located at the center of exiting coil (1 MHz, 3 kA/m-rms). Complex permeability µ' and µ", coercive force Hc, and SPL of the LSMC decreased with increasing the temperature. Phase delay δ of magnetic flux density of the LSMC from the applied magnetic field were almost the same among measured temperature range.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
