This disclosure will describe a novel finding and make the claim for the first time on a group of old compounds and formulated new compounds. These compounds have superconducting property at high temperatures, i.e., 151 K or higher. Several compounds were prepared, though not well-purified, at around middle of 1900s. Their chemical, structural, electric and magnetic properties were studied and reported but their superconducting property has not been known and has never been exploited because the idea of type-II superconductivity was not proposed at that time. The experiments to further verify their high temperature superconductivity require the utilization of sophisticated facilities on synthesizing highly pure compounds and the deregulation from government security authorities on purchasing the starting materials. 1. A device including a material that conducts electricity , the material comprising:{'sub': 'n', 'a compound with a chemical formula (M)(X);'}wherein M is at least one selected from the group consisting of: actinium, thorium, protactinium, uranium, neptunium, plutonium, americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, lawrencium, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium, scandium, titanium, vanadium, chromium, manganese, yttrium, zirconium, niobium, molybdenum, technetium, hafnium, tantalum, tungsten, rhenium, and their isotopes;wherein X is at least one selected from the group consisting of: fluorine, chlorine, bromine, iodine, astatine, oxygen, sulfur, selenium, tellurium, nitrogen, phosphorus, arsenic, antimony, carbon, silicon, germanium, boron, and their isotopes; andn is a value ranging from 0.05 to 20; andthe compound conducts electricity at 151 K or higher.2. The device including a material that conducts electricity of claim 1 , wherein M is two or more elements selected from the group consisting ...
