We discuss X-ray and gamma-ray emissions from Crab-like pulsars, PSRs~J0537-6910 and~J0540-6919, in Large Magellanic Cloud. Fermi-LAT observations have resolved the gamma-ray emissions from these two pulsars and found the pulsed emissions from PSR~J0540-6919. The total pulsed radiation in the X-ray/gamma-ray energy bands of PSR~J0540-6919 is observed with the efficiency $\eta_{J0540}\sim 0.06$ (in 4$\pi$ sr), which is about a factor of ten larger than $\eta_{Crab}\sim 0.006$ of the Crab pulsar… Expand
