\n When magnetic moments are interacting with each other in a situation resembling that of complex love triangles\, called frustration\, a large set of states that are energetic ally equivalent emerge. This leads to exotic spin states such as spin liqu id and spin ice. In their paper recently published in the Proceedings of t he National Academy of Sciences (PNAS)\, we presented evidence for the exi stence of a topological glassy state\, that we call a spin jam\, induced b y quantum fluctuations. The case in point is SrCr9pGa12-9pO19 (SCGO(p))\, a highly frustrated magnet\, in which the magnetic Cr ions form a quasi-tw o-dimensional triangular system of bi-pyramids. This system has been an ar chetype in search for exotic spin states. Understanding the nature of the state has been a great intellectual challenge. Our new experimental data a nd theoretical spin jam model provide for the first time a coherent unders tanding of the phenomenon. Furthermore\, the findings strongly support the possible existence of purely topological glassy states.
