Manganese-containing structures based on this mineral can exhibit “colossal magnetoresistance.” The bismuth and oxygen Aurivillius phase of this mineral exhibits ferroelectricity and is a candidate for low-temperature (10[1])co-fired ceramics. Strontium titanate was (10[1])part of the first series (10[2])of a phase of this mineral named for Ruddlesden and Popper. High-temperature (10[1])superconductors like YBCO (10[1])have structures (10[1])named (10[1])for this mineral. (10[3]-5[3])Metal (10[1])halides (10[1])with structures named for this mineral are commonly used in solar cells. (10[2])The (10[2])D-double-prime (10[2])layer is (10[1])characterized (-5[1])by high-pressure magnesium silicate called the “post” form of this mineral. (10[2])This mineral names (10[1])a structure (10[1])for compounds of the form ABX3. (10[2]-5[1])For 10 points, (10[1])what mineral consisting of calcium titanium (-5[1])oxide is named for a Russian mineralogist? (-5[1])■END■ (10[10]0[18])
