I want to measure a magnetic field and for various reasons (drift, offset, temperature sensitivity and noise) I can't use a HAL-sensor or a magneto-resistive sensor. So I am thinking about using the properties of ferroxcube to measure the field.
From what I have read, the magnetic properties of ferroxcube changes when a magnetic field is applied. So I could build an RF oscillator and measure it's frequency. The oscillator's frequency will then tell me indirectly what the magnetic field strength is.
Has anyone ever tried this?
