Electron spin resonance (ESR) and nuclear magnetic resonance (NMR) measurements atultra-low temperatures below 1 K and at high frequencies have been very important experimentaltechnique for materials science concerned with electron spin, especially in the research field ofcondensed matter physics. Recently, a category "double magnetic resonance" experimentaltechnique involving both ESR and NMR is considered to be a promising tool to give us newpossibility of magnetic resonance, such as dynamic nuclear polarization and ENDOR. In order toconstruct a double resonance measurement system at very low temperature, we have started todevelop a mirror-type microwave cavity in order that we can put additionally an NMR coil arounda sample in the cavity. We report here on our current status of the development of the cavity.
