67 Material 

A high frequency NiZn ferrite for the design of broadband transformers, antennas and HF, high Q Inductor applications up to 50 MHz.  Toroids, multi-aperture cores and antenna/RFID rode are available In this material.

Strong magnetic fields or excessive mechanical stresses may result in irreversible changes in permeability and losses.
