The core of a high-frequency transformer is typically made of ferrite materials to reduce:

ACopper losses in windings
BMechanical friction
CEddy current and hysteresis losses
DStray magnetic flux leakage

Explanation

Ferrites have extremely high electrical resistivity, which dramatically reduces eddy current losses at high operating frequencies.
