Abstract

A high resolution radio frequency technique was used to measure the temperature dependence of the London penetration depth in both single crystal and polycrystalline MgB₂. An exponential temperature dependence was obtained at low temperature, which indicated s-wave pairing. A small energy gap value was obtained and the pairing interaction of the compound was found to be phononic.
