Vibrating Sample Magnetometer and Its Application in Characterisation of Magnetic Property of the Anti Cancer Drug Magnetic Microspheres

The measurement of magnetic moment in magnetic materials is a widespread area of research in both academic and industrial frontier. The magnetic target drug delivery system has various applications in the field of cancer treatment. And its value depends on whether the system possesses super paramagnetic, biocompatibility, effectiveness of drugs and otherwise. A sample is placed inside a uniform magnetic to magnetize the sample. The sample is then physically vibrated sinusoidally, typically through the use of a piezoelectric material. The vibrating sample magnetometer (VSM) measures the magnetization of a small sample of magnetic material placed in an external magnetizing field by converting the dipole field of the sample into an ac electrical signal.
