    "description": "The magnetic space group of a material in Belov-Neronova-Smirnova (BNS) notation.\n\nThe value combines the BNS Hermann-Mauguin symbol with its BNS number in parentheses, for example `Pn'm'a (62.446)`. Primes are rendered as apostrophes, and an overbar is rendered as a leading minus sign.\nA null value means no BNS symbol is available or recorded for this material.",
