Magnetic moments cancel and no Curie temperature exists when all electrons in a material are
Aunpaired outer ones
Bhalf filled ones
Cpaired, opposite spin
Dfree and mobile
Answer & Solution
Correct answer: C. paired, opposite spin
Paired electrons have opposite spins and angular momenta, so their moments cancel.
